Section 1 - Product Overview
Introduction
The D-Link SECURICAM Network DCS-2120 Wireless Internet Camera is a powerful surveillance system that connects
wirelessly to your 802.11b/g network. The DCS-2120 features enhanced 802.11b/g and connects wirelessly at a
rate of up to 54Mbps1 (Megabits per second). The DCS-2120 differs from a conventional PC Camera because it is a
standalone system with a built-in CPU and Web server, providing a low-cost solution capable of solving demanding
security and home/office monitoring needs. Snapshot enables you to save images directly from a Web browser to a
local hard drive without installing any additional software. With 0.5 lux light sensitivity, the DCS-2120 is capable of
capturing video in rooms with minimal lighting. You can also zoom in with the DCS-2120’s 4x digital zoom2 feature. The
DCS-2120 gives you the ability to monitor video and audio in your home/office using an Internet browser from any
where in the world! Simple installation procedures, along with the built-in Web-based interface offers easy integration
to your network environments.
Customers also have the ability to view live video streams from a compatible 3G cell phone. The live camera feed of
the D-Link Wireless Internet Camera can be pulled from the 3G cellular network by using a compatible cell phone with
a 3G video player3. From anywhere within the 3G service area, both consumers and small businesses are offered a
flexible and convenient way to remotely monitor a home or office in real time.
Note: Use of audio or video equipment for recording the image or voice of a person without their knowledge and consent
is prohibited in certain states or jurisdictions. Nothing herein represents a warranty or representation that the D-Link
product provided herein is suitable for the end-user’s intended use under the applicable laws of his or her state. D-Link

Wireless Installation Considerations
The D-Link wireless internet camera lets you access your network using a wireless connection from virtually anywhere
within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location
of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to
maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link adapter and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

compatibility among networking equipment, software, and peripherals. The
DCS-2120 is an UPnP enabled Internet camera. If your operating system is UPnP
enabled, the device will be easier to configure. If you do not want to use the UPnP
functionality, it can be disabled by unchecking the Enabled UPnP checkbox in
the Advanced > Network page (see page 33). Use the following steps to enable
UPnP settings only if you are running Windows® XP. If you are running Windows®
98/2000, UPnP is not available.
